Detailed Description

The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.

As shown in fig. 1 and 2, the utility model discloses a cellulose fiber composite fabric with antibacterial, moisture-absorbing and sweat-releasing functions, which comprises an inner fabric layer 1, a middle porous film layer 2 and an outer fabric layer 3 which are arranged from inside to outside in sequence, wherein the inner fabric layer 1, the middle porous film layer 2 and the outer fabric layer 3 are connected in a compounding manner.

The inner fabric layer 1 is a cellulose acetate antibacterial fabric, the raw material is cotton/cellulose acetate/degradable terylene blended yarn, the fabric is in a knitted mesh structure, so that the fabric has good air permeability and comfort, and the fabric mainly has the functions of antibiosis, deodorization and sweat discharge generated by a human body. PHB, a low degree of polymerization in cellulose, can disrupt the biofilm and cell wall of bacteria, causing leakage of the intracellular material of the bacteria to kill the bacteria. PHB with low degree of polymerization can also destroy lipids and proteins of virus-encapsulated RNA, causing the virus to die. In the antibacterial detection, the whole fabric has better antibacterial property when the content of the cellulose fibers reaches 10% or more, and the content of the cellulose fibers related in the utility model is more than 10%.

As shown in fig. 2, the middle porous film layer 2 is a wet response shape memory porous film, air holes are formed in the wet response shape memory porous film, the air holes are cross-shaped, and the air holes are uniformly distributed in the wet response shape memory porous film. The moisture-responsive shape memory material is capable of undergoing a shape change upon stimulation by external moisture, and the air holes are automatically opened when the external moisture reaches a certain level and are closed in an environment without moisture (in the figures, a and b are dry and wet states, respectively).

The outer fabric layer 3 is made of superfine polyester fiber fabric, the polyester fiber has good hydrophobicity, does not absorb moisture but has strong moisture conducting effect, and meanwhile, the superfine polyester fiber has great relative ratio surface area, so that moisture absorbed in the fabric can be discharged out of the fabric in a short time, and the fabric is kept dry.
